PWR: -108 dbm

That can be the issue: signal level is too much low. Maybe some antenna problem?

It has been a bit intermittent but at the moment is not registering at all
(with two SIMs from two different providers).

I've tried the latest Telit firmware I was sent (17.0.1.522) and the
behaviour is pretty much the same. I'll send a separate mail with the logs.

Hi

According to logs shared by Kelvin, the modem seems to be properly replying


Thanks, yes QMI commands seem to be working now but it fails to register on
a network.

I've tried a SIM card for a different network provider now (EE) and the
scan response is:

The --3gpp-scan is a bit different with this SIM card / network, it shows
'current' for the correct network (EE) and forbidden for the others:

LE910 does not need to have dtr set: the change is needed, instead,
for LE920A4 and other more recent modems that are sharing the same
PID, but need DTR set.

According to logs shared by Kelvin, the modem seems to be properly replying.

Not deliberately - but the development board is typically used on Android,
with Linux/Ubuntu provided as a secondary platform, so I guess there could
be some Android stuff left over in the vendor's Linux kernel.

config MSM_QMI_INTERFACE
depends on IPC_ROUTER
depends on QMI_ENCDEC
bool "MSM QMI Interface Library"
help
  Library to send and receive QMI messages over IPC Router.
  This library provides interface functions to the kernel drivers
  to perform QMI message marshaling and transport them over IPC
  Router.

Thanks,
Kelvin.

CONFIG_MSM_QMI_INTERFACE=y ?

Are you building an Android kernel with both Qualcomm and qmi-wwan

It shows the modem is using regular AT commands, when it should really
be using QMI instead.  What is "lsusb -v -d 1bc7:1201" for this device?

The problem appears to be:

Jan  1 20:48:44 linaro-gnome kernel: [   10.661323] qmi_wwan 1-2.1:1.5: 
bogus CDC Union: master=0, slave=0

Jan  1 20:48:44 linaro-gnome kernel: [   10.661409] qmi_wwan: probe of
1-2.1:1.5 failed with error -1

Bjorn/Carl/others would probably know more about why the probe fails
for this device.  But if you could grab the lsusb -v output I asked for
above, that would help figure it out.

Thanks,
Dan

Re: Telit LE910 failing to find network

Hi Aleksander,

I tried upgrading to modemmanager-1.6.4 and similar results. Comments below.

The same:
"error: couldn't register the modem: 'Timeout was reached"'

With 1.6.4 it still doesn't seem to check for EPS, though I'm not sure if
that matters:

Still not having luck with 1.6.4, even though there are still 11 networks
showing in 3gpp-scan including the on I'm interested in.

Each Telit has 4x ttyUSB devices (I've got 2 connected to this board but
one is not in use, has no SIM card etc).

Thanks a lot for any hints, much appreciated.

Kelvin.
